Description of required skills:
|
UNIT STANDARD RANGE |
The context of this unit standard includes a complete process, from the point of receiving a commodity raw material to the point of supplying a commercially saleable product.
The level assigned to this unit standard is appropriate because the process requires a wide range of cognitive skills and offers a considerable choice of solutions. A broad knowledge base incorporating some theoretical concepts, analytical interpretation of information, informed judgement and a range of sometime innovative responses to concrete but often unfamiliar problems are employed. |

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: |
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here. |
